Auth

Auth¶
Important
Terra’s auth module inherits from Cosmos SDK’s auth module. This document is a stub and covers mainly important Terra-specific notes about how it is used.
Terra’s Auth module extends the functionality from Cosmos SDK’s auth module with a modified ante handler, which applies basic transaction validity checks, such as signatures, nonces, and auxiliary fields. This module also defines a special vesting account type that handles the logic for token vesting from the Luna presale.
Gas Fee¶
Like all transactions on the Terra blockchain, MsgSend and MsgMultiSend incur gas fees. These fees are determined by a validator’s minimum gas price and the complexity of the transaction. More complex transactions incur higher fees. Gas fees are specified by the sender when a transaction is outbound. For more information on how gas is calculated, see fees.
Parameters¶
The subspace for the Auth module is auth.
type Params struct {
MaxMemoCharacters uint64 `json:"max_memo_characters" yaml:"max_memo_characters"`
TxSigLimit uint64 `json:"tx_sig_limit" yaml:"tx_sig_limit"`

SigVerifyCostSecp256k1 uint64 `json:"sig_verify_cost_secp256k1" yaml:"sig_verify_cost_secp256k1"`
}
MaxMemoCharacters¶
The maximum permitted number of characters in the memo of a transaction.
type:
uint64default:
256
TxSigLimit¶
The maximum number of signers in a transaction. A single transaction can have multiple messages and multiple signers. Because the sig verification cost is generally higher than other operations, the number of signers is limited to 100.
type:
uint64default:
100
TxSizeCostPerByte¶
The cost per byte used to compute the gas consumption of a transaction. TxSizeCostPerByte * txsize.
type:
uint64default:
10
